Answer: 10x - 25x - 35
Step-by-step explanation:
F 2x times 5x = 10x
O 2x times 5 = 10x
I -7 times 5x = -35x
L -7 times 5 = -35

Pie is my answer. Or dose have to be 4 letters
Answer:
1,300
Step-by-step explanation:
First, we need to substitute all the variable with the given number.
To figure out the 2 equivalent squares, do 20 x 20 , which is 400.
Then, the 3rd triangle, do 28 x 25 , equaling 700.
Lastly, for the 2 triangles, 20 x 20 / 2 , leading to the solution of 200.
Now, putting everything together by adding 400+700+200, the final answer is 1,300.
I hope this helped!!

Answer:
The error E = ± 4.04 %
Step-by-step explanation:
Solution:-
- The sample data is used to estimate the population proportion ( p ).
- The success p^ = success percentage = 40 %
- The confidence interval CI = 98%
- The sample size n = 800
- The margin of error E:
- The margin of error "E" for estimation of population proportion ( p ) is given by:

Where, Z-critical value is defined by the significance level:
P ( Z < Z-critical ) = α / 2
Where, α : Significance level
α = 1 - CI
P ( Z < Z-critical ) = (1 - 0.98) / 2
P ( Z < Z-critical ) = 0.01
Z-critical = 2.33
- The error E of estimation is:

- The error E = ± 4.04 %
The nearest 10 dollars would be $70.
And 25% of 70 is 17.50
So 17.50 should be correct.
